▎ 摘　　要

NOVELTY - Method for preparing organic-inorganic hybrid separation membrane involves (a) mixing inorganic particles, film-forming polymer, solvent and water into a uniform film casting solution, (b) adjusting the pH value of the casting solution, stirring evenly, and adding a silane crosslinking agent dropwise, and (c) immersing the precipitated phase in water and converting into a membrane to obtain an organic-inorganic hybrid separation membrane. USE - The method is used for preparing organic-inorganic hybrid separation membrane (claimed). ADVANTAGE - The membrane has excellent stability, improved durability, hydrophilicity and mechanical properties.
